A comprehensive study of nearly 200 of the fastest spinning pulsars in the universe has revealed that these cosmic lighthouses emit radio waves from two completely separate locations simultaneously. The discovery challenges the long-held astronomical understanding that pulsars broadcast their signals exclusively from tight beams near their magnetic poles on the surface.
The research demonstrates that pulsar radio emissions originate from both the traditional near-surface location close to the magnetic poles and from a second, previously unknown location at the outer edge of the pulsar's magnetic field influence in space. This dual-emission pattern represents a fundamental shift in how astronomers understand these rapidly rotating neutron stars.
